Patent GB-1501761-A (GB)
Title: Apparatus for regulating the output from an adjustable hydraulic pump
IPC: F04B49/08
Filed: 1975-11-27
Abstract: Pressure medium control for the pressure-actuated piston (13) of the pressure controller is effected via a control valve (23), acting on which there is, on the one hand, the delivery pressure and counter thereto the force of the controller spring (26). Acting on the two opposite faces (F1, F2) of the control valve, in a particular position thereof, there is in addition to the abovementioned forces a fluid pressure force as prevails on the pressure-actuated piston. The fluid pressure force on the control valve end face (F1) facing away from the controller spring is larger in this case, because this end face (F1) is larger than the other end face (F2). As a result, the control valve is returned to its neutral position even before the delivery pressure has reached the desired point. This means that the pressure characteristic curve of the integrally acting pressure controller rises against the output volume, as the resistance to adjustment and the required adjustment pressure increase as the delivery pressure rises; as a result, the stability behaviour of the pressure controller is improved. <IMAGE>

Title: Vapor recovery method and system
IPC: C10G5/06
Filed: 1965-11-22
Abstract: <PICT:1064880/C4-C5/1> Gasoline components are recovered from vapours evolved during the filling of tanks with gasoline by passing the vapours after pre-cooling in heat exchange 13 up through a column 15 firstly over chilling coils 16 to condense and separate any water, and secondly over further coils 17 to condense the hydrocarbon components. The hydrocarbon components form a layer G on top of the water collecting in a well 37, both being withdrawn under control of liquid level controllers 41 and 38.  The temperature of the lower coil 16 is maintained within the range 33 DEG  F. to 35 DEG  F. and the upper coil within the range 20 DEG  F. to 30 DEG  F.  The uncondensed top vapours pass through line 20 to heat exchanger 13 and reduce the temperature of the incoming vapours to 10 DEG  F. below the ambient atmospheric temperature.  The cooling of the coils is effected by an artificial refrigeration unit.  Bodies of porous particulate material 18 and 19 acting as agglomerating agents may be arranged in front of the cooling coils, e.g. alumina-silica particles and alumina particles impregnated with ZnO2.

Abstract: 1493262 Pneumatic power tools; torque wrenches THOR POWER TOOL CO 22 Nov 1975 [23 Nov 1973] 50715/74 Heading B3N A pneumatic power tool such as a torque wrench includes a pneumatic motor 15 fed by an air supply passage extending through handle 11 and a control valve assembly 70 having a valve member 115 movable between two positions respectively permitting and preventing air under pressure to flow to the motor. A piston 144 is slidably mounted in chamber 148 and a spacer 137 is positioned between the valve member 115 and piston 144 to cause movement of one to be transmitted to the other and vice versa. The spacer is rigid and made of plastics material and is lighter in weight than the piston and the valve member. In operation of the nutsetter shown, after a predetermined output torque is reached the torque is supplied in pulses in rapid succession, by rapid opening and closing of valve member 115, to reduce the reaction torque felt by the operator, this being a mean value of the pulsed torque. The motor 15 is a turbine, Fig. 2, comprising a rotor body 19 with axially tapering radial extensions 21 supporting blades 20 outwardly urged by bleed air from the air supply passage 117. Since the motor is to be rapidly switched on and off chambers 24 are quickly exhaustable through passages 155-158, Fig. 5 leading from annular chamber 164 around guide portion 134 of valve member 115, which chamber communicates with chamber 24 when valve member 115 is closed. When pilot valve 73 Fig. 3, is closed by solenoid 103 supply air passing up bleed passage 149 cannot excape through vent passages 152, 83 in the pilot valve 73 to atmosphere but pressurizes chamber 148 to actuate piston 144 and, through spacer 137, valve member 115 to open the valve to allow air to pass from passage 116 to passage 117 and to the motor. When pilot valve 73 is opened, chamber 148 is vented and the reverse happens. An electrical control circuit includes a reaction torque measuring transducer 50, Fig. 1, switches 186 187, Fig. 6 (not shown), operated together by plunger 172, and the circuit of Fig. 7 which is described in Specification 1,493,263.
